Consumer group CHOICE welcomed the NSW decision and said the cost to payment card companies was around a tenth of what they have been charging customers.

"Hopefully this will mean one less industry taking advantage of consumers and flouting the Reserve Bank of Australia's rules, which unfortunately have no regulator enforcing them," CHOICE chief executive Alan Kirkland said.

The central bank last year introduced a set of standards aimed at limiting how much card companies could charge for services, but consumer groups claim the rules have had little impact.

In 2012, CHOICE awarded Cabcharge a "Shonky" award for its 10 per cent card fee.
